We have had the stove for about three weeks and it seems to work well.  I enjoy all the burner choices and the three racks in the oven.  We have used convection a number of times but have yet to use the air fryer feature.  We have 4 children (16-20) that use the oven and I was nervous about the scratching of the cooktop but as of yet, we have had no issue.  It cleans up nicely.
